Church's Chicken / management are liars!

The manager LIED in the Cleveland, MS area and said our free chicken coupon code was invalid in WHICH it was NOT! I did the free coupon code the same day before I went to churches. After I did not receive my chicken, I called and made a complaint and the next morning an Area Manager basically tried to say "I made up a coupon code and need to do it INFRONT of them!" THIS IS NOT THE CUSTOMER IS RIGHT rules as WELL as I actually did the free chicken coupon code! I cannot eat with a chain that employees dishonest PEOPLE! I will not eat at any chain from them nor my family!
